Theres also the soundmagic hp200

Apparently it has more bass impact than the he400 which is known partially for its bass.

Unfortunately, it's very hard to get them where I live, in Sweden :/

Honestly I'd find a dac/amp with a bass boost and use any pair of headphones that you find comfortable. With most of dubstep the highs aren't very important and the bass washes all other frequencies out. Despite this I do listen to dubstep myself so I am not hating on the genre. Just saying it doesn't take much of a headphone, rather a dac to get the most out of the music. 

There's just so many amps out there and I'm new to this, I mean my head goes boom. :S
And also I don't want the bass to control the music/wash the other frequencies out

Sorry, off topic but I couldn't resist:
 

Mozart vs Skrillex

 
 

Haha I've seen that a couple of times, have you seen the Mozart vs Skrillex with a twist?

Nope, didn't know about that. It was the first time I saw that video. That was pretty cool of Skrillex to participate with ERB! It's good that he doesn't take himself too seriously and can have fun with it. Thanks for sharing.

If you really want to buy another pair of headphones for home then what are you expecting? Massive bass? Crystal clarity? Light weight? Durability? etc etc

I'm expecting good bass but not massive, like Beats that's just too much. Maybe not crystal clarity but I'd like it. And they don't have to be lightweight but I'll have them on for long periods so they have to be pretty comfortable, and I'm very careful so I don't need great durability. And I want to hear voices just as well as the bass. Maybe too much for a $250-300 budget :/

I am sure I'm bias on this but the Beyer 250ohm 990's seem like they'd fit that bill. Powerful bass but not boomy and voices sound very good. They are $150 usd on amazon. They are 250g or slightly under 9oz and very comfortable. They do need a decent amp to get the most out of them and they also take 2-3 days to get used to the sound. When you first try them you'll like them and this will be followed by a little fatigue. For most it seems to go around 2-3 days of consistant listening. 

Thank you I'll look at them

German Maestro gmp 8.35d are nice and dont need an amp.

Only downside is I think he wanted open.

If you are looking for headphones for home use that are open back and do not require that much bass, audition the AKG Q701 if you can. They sound very good with excellent soundstage, separation, depth and while the bass is not as loud as closed-back headphones, it is more 'complete' then some other open-back headphones; What I mean by that is for example, the bass from ATH-AD700 rolls off so early sometimes you cannot even hear or notice some of the lower bass notes. With the Q701, the bass does not roll off as early. It will play the bass line completely with good control, it just won't be as loud compared to a closed back headphone. The mids are a bit warm, but you can still hear alot of the details. It sounds fairly neutral compared to other headphones, so it can can sound 'boring' to some.
 
 
You might also want to audition the AKG K272 HD it's a closed back headphone, but they have velour pads and that gives them a considerable soundstage for closed back headphone. Separation isn't as good as the Q701, but it's closed back so it has more bass. With the stock foam disk (that goes behind the ear pad) I thought they sounded slightly muffled and could be improved upon so I modded mine by replacing the foam disk with the larger ones from Beyerdynamic. This mod increases the soundstage. The larger foam disks from the AKG K240 also work, but the Beyerdynamic foam is thinner so you get a clearer sound with them.
 
 
Both the AKGs require a decent amp to sound the best, but I have been able to drive them to sufficient volume plugged in directly to my X-Fi XtremeMusic soundcard, (yes, I know it's an outdated SC) but I have to raise the volume sliders quite a bit.
 
 
These are not the usual recommendations for EDM music, but you said that it doesn't have to require that much bass. For reference, the ATH M50s have more bass than either of the AKGs.
 
Another thing, the Q701 headband have these little bumps that many people don't seem to like. I myself prefer the flat style AKG headband over the bumpy one used in the Q701, so that may be an issue if comfort is a concern.
 
I have also heard positive things about the Superlux HD330. I do not own these, and have not heard them yet but have been very curious about these for awhile. These are also available for a good price in the EU:

Looks like they ship to Sweden too.

Q701's would by no means be good for him... bass is the least represented frequency range here. I'd check into the DT-990's maybe plus a portable amp... a combo I wish to hear myself one of these days.
